Identifying Air Wave Reflections - Radiodetection RD1000 Operation Manual

3.4.3 Identifying Air Wave Reflections

Some arches in the image can be caused by objects that are not
in the subsurface, such as posts, fences, overhead wires and even
trees.
An important part of understanding the data image is learning to
recognize these unwanted "air" targets and differentiate them from
the targets in the ground.
One way of identifying air reflections is to use the target arch
method described above. However, arches from above-ground
objects are wider than objects in the ground and out of the range of
the maximum Soil Type.
Therefore, if the widest Indicator Arch is still not wide enough to
match the target arch, the target arch is from on object in the air,
not the ground.
